In order to facilitate description and render accurate expressions,several related terms are first explained herein:

A side surface or a side wall of the impeller and a side surface or aside wall of the machine housing to which an axis of the impeller isdirected are referred to as an axial side or an axial side wall.

A side of the impeller or a machine body toward a motor (or other powercomponent) is referred to as an axial rear side, the counterpart side isreferred to as an axial front side, and an axial backward direction andan axial forward direction can be inferred therefrom accordingly.

A part near the axis of the impeller is a radial front part of theimpeller, an front end of the radial front part is a radial front end ofthe impeller; a part near a periphery of the impeller is a radial rearpart of the impeller, and an edge of the periphery of the impeller is aradial rear end of the impeller (indications of other relevant parts ofthe machine housing can be inferred therefrom accordingly). The rotationdirection of the impeller is an axial direction, the direction as theimpeller rotates is a forward direction of rotation or an axial forwarddirection, the direction opposite the impeller rotation is a backwarddirection of rotation or an axial backward direction, a side surface ofthe blade in the same direction as the impeller rotation is an axialfront side surface, a side face of the blade in a direction opposite theimpeller rotation is an axial rear side surface, indications of otherrelevant parts of the machine body can be inferred therefromaccordingly.

Indications of directions in the machine housing air inlet: the entranceof the machine housing air inlet is front, the exit of the machinehousing air inlet is rear, indications of other directions in themachine housing air inlet can be inferred therefrom accordingly.

The radial inlet of the blade is an air flow inlet formed at the radialfront end of the blade.

The axial inlet of the blade is an air flow inlet formed at the axialside surface of the blade. Such as a negative pressure gap of theimpeller of a backward flow blower, a synchronous forward flow air inletof the impeller of a synchronous backward flow blower, etc.

The blade working surface is the side surface of the blade which rotatesaxially in the same direction as the impeller, and the axial front sidesurface of the blade can also be referred to as the blade workingsurface.

The impeller flow channel refers to an impeller inner-side channel and ablade flow channel; the blade is a through-flow component, and the bladeflow channel is the blade itself.

The through-flow component in the machine body refers to a componentthrough which gas to be processed and processed passes, such as amachine housing air inlet, an impeller, an impeller air inlet, animpeller air outlet, impeller blades, a machine housing inner-sidechannel, a machine housing air outlet, etc.

According to the high-temperature hot air blower capable of gatheringenergy and generating heat of the invention, a pneumatic energyconversion heat-generating mechanism is adopted, cold air is directlyprocessed into hot air, any heat source or heat medium (electric heatingwires, electric heating tubes, electric heating plates, coal furnaces,oil furnaces, gas furnaces, etc.) is not required, the hot air bloweroperates solely by itself to convert mechanical energy into thermalenergy, which is then discharged through an air outlet of the hot airblower for use. The high-temperature hot air blower capable of gatheringenergy and generating heat adopts a gas collision & friction &stagnation heat-generating mechanism to promote energy conversion frommechanical energy to thermal energy, generates heat, increases gastemperature and produces high-temperature hot air. The so-called gascollision & stagnation heat-generating mechanism refers to the fact thatone or more high-speed gas flows collide each other by being ejectedagainst or cross each other, or one or more high-speed gas flows collideagainst flow channel parts, or the mechanical energy of the gas flowspromotes internal friction of the flow channel parts, decelerates anddecompresses, and the pressure reduced by the gas flows converts thespeed energy (kinetic energy) into thermal energy to generate heat andproduce high-temperature hot air.

Various existing ventilators, blowers, gas compressors, compressors andthe like can only produce cold air, and compared with these variousmachines, the high-temperature hot air blower capable of gatheringenergy and generating heat can produce hot air, that is, compared withthe cold air machine, the hot air blower is suitable for production andlife where hot air is required.

Like the existing cold air machines such as various ventilators, blowersand the like, the hot air blower of the invention also has various sizesincluding large, medium and small, from tens of watts to tens ofkilowatts, hundreds of kilowatts and thousands of kilowatts, with thegenerated air volume from a few cubic meters per second, tens of cubicmeters per second to hundreds of cubic meters per second; the generatedair pressure can be tens of Pa, hundreds of Pa, thousands of Pa and tensof thousands of Pa; the temperature of the generated hot air may beseveral degrees Celsius, tens of degrees Celsius, and hundreds ofdegrees Celsius. The hot air blower of the invention has multiplefunctions and wide applications suitable for various scenarios, isenvironmental friendly, and satisfies requirements of heating, heatpreservation, drying, baking food processing, warmth-keeping andgrowth-facilitating for agricultural fruits and vegetables ingreenhouses, domesticated livestock and fishery aquatic products,industrial high-temperature paint spraying, product processing and thelike in various fields in production and life, where this hot air blowercan take the place of the cold air machine. The hot air blower is moreenergy-saving than the cold air machine, which is beneficial toenvironmental protection.

According to the invention, the energy-gathering heat generator isprovided on the side wall of the machine housing inner-side channel, theenergy-gathering heat generator comprises the heat generatortransmission protective cover, the heat generator frictionheat-generation body, and the heat generator heat-insulation isolationwall; the heat generator transmission protective cover is disposedoutside the energy-gathering heat generator and is connected with theheat generator friction heat-generation body with their side surfacesattached; the heat generator transmission protective cover is composedof tough and resilient materials (such as plastic plates, nylon plates,nylon cloth, synthetic fiber fabrics, plush, ceramics, cotton cloth,gold silk fabrics, leather, liquid glue, paint and the like) with goodheat transfer performance. The heat generator transmission protectivecover prevents high-speed air flow from directly colliding against theheat generator friction heat-generation body and protects the heatgenerator friction heat-generation body from being worn and broken; theheat generator transmission protective cover directly receives theimpact of the high-speed air flow, directly transfers mechanical energydelivered by the high-speed air flow to the heat generator frictionheat-generation body, and promotes the heat generator frictionheat-generation body to generate heat through internal layer friction.Moreover, the heat generated by the heat generator frictionheat-generation body can be rapidly transferred to the gas in themachine housing inner-side channel from inside to outside, thetemperature of the gas is increased, and high-temperature hot air isproduced.

The heat generator friction heat-generation body is disposed inside theenergy-gathering heat generator, the outer side surface of the heatgenerator friction heat-generation body is in fit connection with theheat generator transmission protective cover, and the bottom surface ofthe heat generator friction heat-generation body is in fit connectionwith the heat generator heat-insulation isolation wall. The heatgenerator friction heat-generation body is composed of soft and elasticdamping materials (soft rubber, sponge, soft plastic foam film, cotton,fluff, ceramic wool and the like). The structure of the heat generatorfriction heat-generation body is larger in thickness and volume than theheat generator transmission protective cover and the heat generatorheat-insulation isolation wall, has a good damping function, and afterexternal force is absorbed, the structure can cause intense internallayer friction, convert mechanical energy into thermal energy andgenerate heat. The heat generator friction heat-generation body is themain core component of the energy-gathering heat generator. Theenergy-gathering heat generator mainly depends on the heat generatorfriction heat-generation body to generate heat, so as to increase thegas temperature.

The heat generator heat-insulation isolation wall is arranged outsidethe bottom surface of the energy-gathering heat generator, one sidesurface of the heat generator heat-insulation isolation wall is in fitconnection with the bottom surface of the heat generator frictionheat-generation body, the other side surface of the heat generatorheat-insulation isolation wall is in fit connection with the machinehousing via the side wall of the inner-side channel (or the outersurface of other parts of the machine housing), and the wholeenergy-gathering heat generator is connected with the side wall of theinner-side channel of the machine housing (or the outer surface of otherparts of the machine housing)via the heat generator heat-insulationisolation wall. The heat generator heat-insulation isolation wall iscomposed of a highly tough heat insulation material (such as heatinsulation rubber, heat insulation adhesive tape, glass fabric and thelike). The heat generator heat-insulation isolation wall is disposedbetween the side walls (or the outer surfaces of other parts of themachine body) of the machine housing inner-side channels, so that theheat generated by the heat generator friction heat-generation body canbe prevented from being transferred to the side walls (or the outersurfaces of other parts of the machine body) of the machine housinginner-side channel and out of the machine body, so that the heatgenerated by the heat generator friction heat-generation body isguaranteed to be transferred to the gas in the machine housinginner-side channel by the heat generator transmission protective cover,and to increase the gas temperature in the machine housing inner-sidechannel.

During operation, the high-pressure high-speed air flow discharged bythe impeller of the blower directly impacts the heat generatortransmission protective cover of the energy-gathering heat generator onthe side wall of the machine housing inner-side channel, so the heatgenerator transmission protective cover presses against the heatgenerator friction heat-generation body and transfers pressure powerenergy to the heat generator friction heat-generation body; after theheat generator friction heat-generation body absorbs the pressure powermechanical energy, intense internal layer friction is caused, with themechanical energy converted into thermal energy, to generate heat. Theheat generated by the heat generator friction heat-generation body isnot transferred to the side wall of the machine housing inner-sidechannel to be dissipated outside the machine body by virtue of the heatinsulation and isolation effect of the heat generator heat-insulationisolation wall, and the heat generated by the heat generator frictionheat-generation body is mainly transferred to the high-pressurehigh-speed air flow in the machine housing inner-side channel by meansof the heat generator transmission protective cover, so that thetemperature of the air flow in the machine housing inner-side channel isincreased and high-temperature hot air is produced.

Higher-pressure and higher-speed of the air flow discharged by theimpeller to the machine housing inner-side channel would render moreintense internal layer friction in the heat generator frictionheat-generation body, and more heat is generated; so more heat isobtained by the air flow in the machine housing inner-side channel, andhigher temperature is obtained. A more soft and elastic heat generatorfriction heat-generation body indicates a larger damping coefficient,and a larger damping coefficient of the energy-gathering heat generatorwould result in better damping friction heat generating effect, and moreheat is generated, and greater temperature rise of the gas is obtained.

The pressure power mechanical energy carried by the high-pressurehigh-speed air flow is gathered at the heat generator frictionheat-generation body in the energy-gathering heat generator, and isconverted into thermal energy through friction to generate heat. Thus,the hot air blower is named as the energy-gathering heat-generatinghigh-temperature hot air blower.

The energy-gathering heat generator is disposed on the side wall of themachine housing inner-side channel, which means that theenergy-gathering heat generator can be disposed on the radial side wall(including a spiral tongue) of the machine housing inner-side channelindependently, the energy-gathering heat generator can be disposed onthe axial side wall of the machine housing inner-side channelindependently, and the energy-gathering heat generators can be arrangedon the axial side wall and the radial side wall of the machine housinginner-side channel simultaneously.

If the energy-gathering heat generator is disposed independently on theradial side wall or the axial side wall of the machine housinginner-side channel, the high-pressure high-speed air flow discharged bythe impeller to the machine housing inner-side channel impacts theenergy-gathering heat generator at one side surface or two side surfacesthereof, and partial mechanical energy of partial air flow of thehigh-pressure high-speed air flow discharged by the impeller to themachine housing inner-side channel is converted into thermal energy. Ifthe energy-gathering heat generators are arranged on both the radialside wall and the axial side wall of the machine housing inner-sidechannel, most high-pressure high-speed air flow discharged by theimpeller to the machine housing inner-side channel simultaneouslyimpacts the energy-gathering heat generator, most of pressure powermechanical energy is converted into thermal energy through friction, sothat more heat can be generated, and the temperature of the gas isfurther increased.

In order to further enhance the heat generation effect to generate moreheat, the energy-gathering heat generator can also be disposed on theinner side surface of the blade disc, this energy-gathering heatgenerator has the same structural mechanism and performancecharacteristics as the energy-gathering heat generator disposed on theside wall of the machine housing inner-side channel; theenergy-gathering heat generator is in fit connection with the inner sidesurface of the blade disc and prevents the high-pressure high-speed airflow from directly impacting the outer side surface of the impeller; theimpact of the high-pressure high-speed air flow is directly absorbed,and the absorbed pressure power mechanical energy promotes friction togenerate heat.

The energy-gathering heat generator can also be disposed on the outerside surface of the blade by wrapping the blade, and is in fitconnection with the blade; the structure, performance and function ofthe energy-gathering heat generator are the same as those of theenergy-gathering heat generator disposed on the side wall of the machinehousing inner-side channel.

If both the inner side surface and the outer side surface of the bladedisc of the impeller are simultaneously provided with theenergy-gathering heat generator, the wall of the inner-side channel ofthe impeller is formed completely by the energy-gathering heatgenerator, and during operation, high-speed air flow produced by theblades impacts the energy-gathering heat generator from four directionsor three directions (a disc impeller without the front blade) throughthe inner-side channel of the impeller, so that the peripheral side wallof the inner-side channel of the impeller can absorb mechanical energyto generate heat by friction.

According to the invention, the energy-gathering heat generators can bearranged at the machine housing air inlet and the machine housing airoutlet respectively or simultaneously, the energy-gathering heatgenerator is respectively supported on the inner side surfaces of themachine housing air inlet and the machine housing air outlet in a liningmanner; and the structure, performance and effect of theenergy-gathering heat generator are the same as those of theenergy-gathering heat generator on the side wall of the machine housinginner-side channel.

According to the invention, no matter to the energy-gathering heatgenerator on the side wall of the machine housing inner-side channel orthe energy-gathering heat generator on the impeller and on the blade, aswell as the energy-gathering heat generator inside the air inlet and theair outlet of the machine housing, the outer surface of the heatgenerator transmission protective cover can be configured as a smoothand flat structure, but can also be configured as an uneven structure.In the case of the outer surface of the heat generator transmissionprotective cover is smooth and flat, high-pressure high-speed air flowcan smoothly pass through the surface of the heat generator transmissionprotective cover during operation, and intense internal layer frictioncan be caused in the heat generator friction heat-generation body togenerate heat. In the case of the outer surface of the heat generatortransmission protective cover is an uneven structure, great resistancecan be generated against high-pressure high-speed air flow duringoperation. Heat can be generated by friction, and the temperature of thegas in the machine housing inner-side channel is increased.

The outer side surface of the heat generator friction heat-generationbody of the energy-gathering heat generator can be configured as a flatstructure or an uneven structure, and in the case of the outer sidesurface of the heat generator friction heat-generation body isconfigured as an uneven structure, the convex part (the convex part iscalled a convex point of the heat generator friction heat-generationbody, the concave part is called a concave point of the heat generatorfriction heat-generation body) is too high and too large, and thesurface of the convex point is also uneven, and the heat generatortransmission protective cover is also in an uneven structurecorresponding thereto, during operation, the whole energy-gathering heatgenerator can generate more heat by means of four kind of intensefriction of the heat generator transmission protective cover, interiorof the heat generator friction heat-generation body, interior andexterior of the convex point of the heat generator frictionheat-generation body, so that the temperature of gas can be increasedfurther.

In summary, the high-temperature hot air blower capable of gatheringenergy and generating heat can fully and effectively decompress anddecelerate the high-pressure high-speed air flow produced by theimpeller of the blower to generate heat to form high-temperature hot airby virtue of the energy-gathering heat generator and the dampingfunction of the heat generator friction heat-generation body of theenergy-gathering heat generator.

Noise of the blower can be sufficiently and effectively reduced byutilizing the damping function of the friction heat-generator, soundwaves of the noise excited during the hot air blower works have certainmechanical energy, when the sound waves impact the energy-gathering heatgenerator, friction heat generated inside the energy-gathering heatgenerator (the heat generator friction heat-generation body of theenergy-gathering heat generator) can be facilitated, with the mechanicalenergy converted into thermal energy, so that part of the sound wavescan be reduced or eliminated, and as a result, the noise is reduced oreliminated.

In addition, the heat generator transmission protective cover of theenergy-gathering heat generator is tough and resilient, when impacted bythe high-pressure high-speed air flow, the heat generator transmissionprotective cover can effectively reduce the pressure of the heatgenerator friction heat-generation body and enable the air flow tocontinue in one direction under decompression and deceleration, reverseair flow due to collision can not be generated, and thus noise due tocollision and friction between the reverse and forward air flow can beavoided, that is, the energy-gathering heat generator can reduce theprobability of noise produced by high-pressure high-speed air flow, andcontrols the blower to produce only a limited and low level of noise.

The energy-gathering heat generator can not only control the blower toproduce limited and low level of noise, but also further absorb andreduce the limited and low level of noise caused by air flow of theblower to even lower noise.

In summary, the energy-gathering heat generator can not only enable theblower to generate heat, but also enable the blower to reduce noise; animproved energy-saving and emission-reducing high-temperature hot airblower capable of gathering energy and generating heat product can bedeveloped by betterment of the energy-gathering heat generatortechnology.

According to the invention, the energy-gathering heat generator can berespectively or simultaneously arranged on the side wall of the machinehousing inner-side channel, on the blade disc, on the blade, in themachine housing air inlet, in the machine housing air outlet and otherflow channel parts.

According to the invention, if a wind-shielding heat generator isdisposed in the flow channel inside the machine housing, and theenergy-gathering heat generator is disposed on the wind-shielding heatgenerator (the side wall of the energy-gathering heat generator is infit connection with the side wall of the wind-shielding heat generatoror wraps the wind-shielding heat generator), the high-pressurehigh-speed air flow can generate better friction effect upon collisionon the energy-gathering heat generator, generate more heat, producehigh-temperature hot air with higher temperature, and simultaneouslyeffectively reduce noise.

In order to enable the heat generated by the heat generator frictionheat-generation body of the energy-gathering heat generator to betransferred to the gas in the machine housing inner-side channel as soonas possible, a special heat conducting element (metal wire or metalsheet with good heat transfer performance and the like) can also beprovided inside the heat generator friction heat-generation body. Theheat conducting element is also directly connected with the heatgenerator transmission protective cover, and the heat generatortransmission protective cover absorbs the heat generated by the heatgenerator friction heat-generation body through the special heatconducting element and then transmits the heat to the gas in the machinehousing inner-side channel.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, the technical solution of the present invention will bedescribed in detail with reference to the accompanying drawings:

Embodiment 1

With reference to FIGS. 1 to 6, a high-temperature hot air blowercapable of gathering energy and generating heat comprises a machinehousing 1, a machine housing air inlet 2, a machine housing air outlet3, an impeller 4, an impeller air inlet 5, an impeller air outlet 6,blades 7, a blade disc 8, an impeller shaft sleeve 9, an impellerinner-side channel 10, a machine housing inner-side channel 11, a radialside wall of the machine housing inner-side channel 12 and an axial sidewall of the machine housing inner-side channel 12. The impeller 4 is ofa single blade disc structure, the whole impeller 4 is not provided witha front blade disc, the blades 7 are blades of an impeller of a backwardflow blower, and the energy-gathering heat generators 13 are adheredwith both the radial side wall 12 (including a spiral tongue) of themachine housing inner-side channel 11 and the axial side wall 12 of themachine housing inner-side channel 11. The energy-gathering heatgenerator 13 comprises a heat generator transmission protective cover 14made of a resilient nylon thin plate with good flexibility and heatconducting performance, a heat generator friction heat-generation body15 made of a soft rubber thick plate with good flexibility and dampingperformance, and a heat generator heat-insulation isolation wall 16 madeof a highly tough rubber thin plate with good heat insulationperformance. And the heat generator transmission protective cover 14 isdisposed outside the energy-gathering heat generator 13 and is looselyadhered with the heat generator friction heat-generation body 15. Theheat generator friction heat-generation body 15 is disposed inside theenergy-gathering heat generator 13, the outer side surface of the heatgenerator friction heat-generation body 15 is adhered with the heatgenerator transmission protective cover 14, and the bottom surface ofthe heat generator friction heat-generation body 15 is adhered with theheat generator heat-insulation isolation wall 16. The heat generatorheat-insulation isolation wall 16 is disposed outer side of the bottomsurface of the energy-gathering heat generator 13, the upper surface ofthe heat generator heat-insulation isolation wall 16 is adhered with thefriction heat-generator 15, and the bottom surface of the heat generatorheat-insulation isolation wall 16 is adhered with the bottom surface ofthe side wall 12 of the machine housing inner-side channel; the wholeenergy-gathering heat generator 13 is connected to the machine housinginner-side channel by means of a heat generator heat-insulationisolation wall 16.

The machine housing of this Embodiment is of a general low-heat andlarge-flow structure, the axial size of the machine housing is large,the calibers of the air inlet 2 and the air outlet 3 of the machinehousing are large, and the shaft of the motor 21 is connected with theimpeller shaft sleeve 9.

During operation, the motor 21 drives the impeller 4 to rotate at a highspeed, the impeller which rotates at a high speed draws in cold airthrough the impeller air inlet 5 and the machine housing air inlet 2 toproduce high-pressure high-speed air flow, and the high-pressurehigh-speed air flow is discharged from the impeller air outlet 6 to themachine housing inner-side channel 11. During flow process, thehigh-pressure high-speed air flow in the machine housing inner-sidechannel 11 continuously impacts the heat generator transmissionprotective cover 14 of the energy-gathering heat generators 13 on theradial side wall 12 of the machine housing inner-side channel and theaxial side wall 12 of the machine housing inner-side channel, so thatthe heat generator transmission protective cover 14 presses against theheat generator friction heat-generation body 15 and transfers pressurepower energy to the heat generator friction heat-generation body 15; andthe heat generator friction heat-generation body 15 absorbs the pressurepower mechanical energy, and converts it to thermal energy by intenseinternal layer friction to generate heat. By virtue of the heatinsulation effect of the heat generator heat-insulation isolation wall16, the heat generated by the heat generator friction heat-generationbody will not be transferred to the side wall 12 of the machine housinginner-side channel to be dissipated outside the machine housing. Theheat generated by the heat generator friction heat-generation body 15 istransferred to the high-pressure high-speed gas in the machine housinginner-side channel 11 through the heat generator transmission protectivecover 14, so that the temperature of the high-temperature high-speed gasis increased to produce high-temperature hot air, and thehigh-temperature hot air is discharged out of the machine housingthrough the air outlet 3 of the machine housing to be used for otherpurposes.

In this Embodiment, the heat generator transmission protective cover 14of the energy-gathering heat generator 13 is loose, soft and elastic,the heat generator friction heat-generation body 15 is soft, elastic andthick, so when the heat generator transmission protective cover 14 isimpacted and collided by high-pressure high-speed air flow, the heatgenerator transmission protective cover 14 continuously presses the heatgenerator friction heat-generation body 15 which contracts and rubsagainst the heat generator transmission protective cover 14, so that thehigh-speed air flow can be facilitated to continue in one directionunder decompression and deceleration, reverse air flow due to collisionand friction would not rise from the unidirectional air flow, and thusnoise due to collision and friction between the reverse and forward airflow can be avoided. On the other hand, because the heat generatorfriction heat-generation body has a good damping function, the noisesound wave excited by the high-pressure high-speed air flow originallyhas certain mechanical energy, and when the noise sound wave impacts thesoft and elastic heat generator transmission protective cover 14, thenoise sound wave mechanical energy is transmitted through the heatgenerator transmission protective cover 14 to the heat generatorfriction heat-generation body 15, so that the heat generator frictionheat-generation body 15 generates heat by internal layer friction, withthe mechanical energy converted to thermal energy; part of the noisesound waves are thereby reduced and eliminated, resulting in reducednoise by using the machine.

In this Embodiment, by means of the energy-gathering and heat-generatingfunction of the energy-gathering heat generator 13 through friction,required high-temperature hot air can be produced, with good processingeffect, high efficiency, low noise, and being beneficial toenvironmental protection.

This Embodiment is suitable for manufacturing the low-pressure high-flowhigh-temperature hot air blower capable of gathering energy andgenerating heat for heating, greenhouse cultivation and otherapplications.

For simplicity and convenience in processing, in this Embodiment, theenergy-gathering heat generator 13 can be directly made of a soft rubberplate, the bottom side of the soft rubber plate is coated with a layerof high-temperature-resistant heat-insulation liquid glue or paint, andis adhered with the side wall of the machine housing inner-side channelthrough the liquid glue or paint, the liquid glue or paint itself is theheat generator heat-insulation isolation wall 15.

The high-temperature hot air isdischarged to the impeller 4, processed by the impeller 4 to increasepressure and speed, and then discharged to the machine housinginner-side channel 11 to impact the heat generator transmissionprotective cover 14 of the energy-gathering heat generator 13 on theside wall of the machine housing inner-side channel, so that the unevenheat generator transmission protective cover 14 generates heat, (intensefriction occurs between artificial filaments and wool filaments, andbetween wool filaments and gas), the heat generator frictionheat-generation body 15 generates heat by intense friction, and thus thetemperature of the gas is increased. The high-temperature hot air entersthe air outlet 3 of the machine housing, subjected to intense frictionof the heat generator friction heat-generation body 15 of theenergy-gathering heat generator 13 in the air outlet 3 of the machinehousing to generate heat, thereby increasing the temperature of the airfurther, forms high-temperature hot air with higher temperature which isthen discharged from the machine body to serve other purposes.

During operation, the high-speed cold air drawn in the machine housingair inlet 2 is processed by the internal layer upper surface of thesponge heat generator friction heat-generation body 15 and the heatgenerator transmission protective cover 14 of the energy-gathering heatgenerator 13 in the machine housing air inlet 2 to form high-temperaturehot air, the high-temperature hot air is pressurized and accelerated bythe impeller to form high-pressure high-speed high-temperature hot air,and the high-pressure high-speed high-temperature hot air enters themachine housing inner-side channel 11, passes through the heat generatorfriction heat-generation body 15 and the heat generator transmissionprotective cover 14 of the energy-gathering heat generator 13 on theside wall 12 of the machine housing inner-side channel to process againto generate heat, the high-pressure high-speed hot air also impacts theenergy-gathering heat generator 13 on the wind-shielding heat generator19 in the machine housing inner-side channel 11, subjected to the heatgenerator friction heat-generation body 15 and the heat generatortransmission protective cover 14 of the energy-gathering heat generator13 on the wind-shielding heat generator 19 to process again to generateheat to form the ultra-high-temperature hot air with higher temperature.The high-pressure high-speed ultra-high-temperature hot air is subjectedto once again processing heat generation by passing through the frictionheat generation body 15 and the heat generator transmission protectivecover 14 of the energy-gathering heat generator 13 in the machinehousing air outlet 3 to generate heat, the temperature is furtherincreased, the high-pressure high-speed ultra-high-temperature hot airbecomes ultra-high-temperature hot air with even higher temperaturewhich is then discharged out of the machine body for use.

In this Embodiment, the heat generator friction heat-generation body 15of all the energy-gathering heat generators 13 are made ofhigh-temperature-resistant sponge products, whose damping frictionheat-generating effect and sound-reducing effect are better, therefore,more heat is generated, the air temperature increases further (>200° C.)to form ultra-high-temperature hot air with higher temperature; and thenoise generated in the operation process of this Embodiment is low,without causing noise pollution.
